Create a PasswordBoxEdit

XAML

<Window ...
    xmlns:dxe="http://schemas.devexpress.com/winfx/2008/xaml/editors">

<dxe:PasswordBoxEdit 
    ShowCapsLockWarningToolTip="True"
    NullValue="" 
    NullText="Please enter your password..." />

Use the Password property to get a password entered by an end user.

Handle the BaseEdit.EditValueChanged event to get a notification when the editor’s value is changed. To validate the new value, handle the BaseEdit.Validate event.

Password Char

Use the PasswordChar property to specify any character that is masked in the password box.

CapsLock Warning

If the Caps Lock is turned on and the mouse pointer rests over the password box editor, the editor can display a warning tooltip. Set the ShowCapsLockWarningToolTip property to true to display the CapsLock warning tooltip.

To provide custom content for the warning tooltip, use the CapsLockWarningToolTipTemplate property.

Password Strength and Requirements

You can use the TextEditBase.MaxLength property to limit the length of a password typed by an end user.

The password strength is automatically estimated and returned by the PasswordStrength property. To manually estimate password strength, handle the CustomPasswordStrength event. The event parameter allows you to obtain the text currently entered by an end user (PasswordStrengthEventArgs.Password) and specify the password strength (PasswordStrengthEventArgs.PasswordStrength).

Xaml

<dx:ThemedWindow ...
        xmlns:dxe="http://schemas.devexpress.com/winfx/2008/xaml/editors"
        xmlns:dx="http://schemas.devexpress.com/winfx/2008/xaml/core"
        dx:ThemeManager.Theme="Office2019Colorful">
    <Grid>
        <StackPanel Orientation="Horizontal" VerticalAlignment="Top">
            <dxe:PasswordBoxEdit x:Name="pwd" />
            <!-- Label content is bound to the PasswordBoxEdit's PasswordStrength property -->
            <Label Content="{DXBinding @e(pwd).PasswordStrength.ToString()}" Margin="10,0,0,0" />
        </StackPanel>
    </Grid>
</dx:ThemedWindow>

“Show Password” Button

Users can press and hold the “Show Password” button to display the concealed characters. Use the ShowPasswordButtonVisibility property to control the button’s visibility as follows:

Property	Description
None	The button is hidden.
Auto	The button is visible when the control’s value is not empty.
Always	The button is visible.

XAML

<Window ...
    xmlns:dxe="http://schemas.devexpress.com/winfx/2008/xaml/editors">
    <StackPanel>
        <dxe:PasswordBoxEdit ShowPasswordButtonVisibility="Auto" />
    </StackPanel>
</Window>

The control’s edit box is read-only while you display the concealed password characters.

Show/Hide Password From Code

Call the ShowPassword()/HidePassword() to show/hide the PasswordBoxEdit‘s password programmatically.

Customize the “Show Password” Button

Use the ShowPasswordButtonTemplate property to specify the template for the “Show Password” button:

XAML

<Window ...
    xmlns:dxe="http://schemas.devexpress.com/winfx/2008/xaml/editors">
    <StackPanel>
        <dxe:PasswordBoxEdit ShowPasswordButtonVisibility="Auto">
            <dxe:PasswordBoxEdit.ShowPasswordButtonTemplate>
                <DataTemplate>
                    <TextBlock Text="Show Password" />
                </DataTemplate>
            </dxe:PasswordBoxEdit.ShowPasswordButtonTemplate>
        </dxe:PasswordBoxEdit>
    </StackPanel>
</Window>
